What is a Pressure Vacuum Valve? Ensuring Tank Safety and Compliance at Sea
The Function of a Pressure Vacuum Valve A pressure vacuum valve (PV valve) is designed to automatically regulate the internal pressure of a ship’s cargo tank. When pressure builds up beyond the set limit, the valve opens to release vapour into the atmosphere. Conversely, when a vacuum forms – for example, during cargo unloading or…
